Technical Field
The invention relates to a damper assembly, in particular for a flap fitting, comprising a first spring holder and a second spring holder, between which at least two springs, which are designed as helical springs, are arranged, and to a flap fitting, in particular for furniture, comprising a housing which can be fixed to a body, on which housing a support rod is rotatably mounted, and a pivotably mounted control rod, wherein the support rod and the control rod can be connected in an articulated manner to a flap via spaced-apart rotational axes, wherein the flap is pretensioned at least over a part of the range of motion via an energy accumulator.
Background
EP 2138658B 1 discloses a flap fitting for a furniture flap, wherein the furniture flap is pivoted via an actuating arm and a control lever. The furniture flap is pretensioned in the closing direction by a tension spring. In order to lift the furniture flap of such flap fittings, energy accumulators are required which are intended to absorb high forces in a compact design. In addition, the user is often annoyed by a loud impact sound.
Disclosure of Invention
It is therefore an object of the present invention to create a damper assembly, in particular for flap fittings, which provides a high force for holding and closing a movable part, in particular a furniture part, in a compact design.
This object is solved by a damper assembly having the features of claim 1. In addition, a flap fitting is created with such a damper assembly having the features of
In the damper assembly according to the invention, at least two springs in the form of helical springs are provided, in each of which a linear damper with a damper housing and a piston rod which is displaceable relative to the damper housing are arranged. This means that a large pretension force can be applied on the damper assembly, wherein the damper prevents high accelerations and generates a corresponding braking or damping force. The spring and the damper can thus improve the ease of operation, in particular within the short travel distance required for the flap fitting, and have a very compact design.
Preferably, the first and second spring holders are designed as dimensionally stable supports on which the damper and the spring are mounted. At least three springs, for example four springs, are preferably provided in order to generate a high pretension force, for example to balance the gravitational forces in the pivotable flap. The spring may be designed as a compression spring or as a tension spring.
In order to avoid lateral forces caused by the damper assembly, the damper assembly is preferably formed symmetrically with respect to the center plane with respect to the arrangement of the springs.
In order to avoid a loud impact sound, it is preferred to fix the damper housing to the first spring holder and the piston rod to the second spring holder. An elastic stop is arranged between the receiving portion and the second spring holder, which elastic stop can be placed directly against the spring holder or against a component connected to the spring holder in the end position. The stopper may be fixed to the second spring holder or to the end of the receiving portion to avoid an annoying impact sound.
In another embodiment, the spring holders are connected to each other by additional linear guides without dampers, for example sliding elements guided on guide rails, which are arranged outside or inside the spring.
In order to generate different damping forces, the damper housing can have different regions with different diameters in a piston working chamber in which a piston of the damper is linearly displaceable.
According to the invention, a flap fitting with a damper assembly is also provided, wherein the flap fitting has a housing which can be fixed to the body, a rotatable support rod and a pivotably mounted control rod, wherein the support rod and the control rod can be connected to the flap in an articulated manner via spaced-apart rotational axes. This means that the damper assembly can be used to comfortably design the movement sequence of the flaps, in particular with regard to closing and opening the flaps.
The damper assembly is preferably used to slow the closing movement of the damper before it reaches the closed position. Preferably, the energy accumulator serves to pretension the flap in the closing direction in the closed position and to pretension the flap in the opening direction in the opening range. The user can then overcome the dead point when opening the flap, and after overcoming the dead point, the flap can be moved in the opening direction under the action of the spring force or automatically. On the contrary, after overcoming the dead point, the flap is automatically moved in the closing direction and is then braked by the damper. In the intermediate position of the flap (which may be before and/or after the dead-center position), the flap may also be balanced such that the flap does not independently perform any closing or opening movement in the intermediate opening range.
To achieve precise actuation of the damper assembly, the spring holder is preferably coupled to the control rod via a curved guide. The curved guide may be actuated via a gear unit driven by a control lever. Gears, pivot levers or other gear elements may be used as the gear unit.
